Kinetic-Molecular Theory To explain the existence of states of matter and changes of phase, we use a microscopic model of matter. The kinetic theory of matter states that the matter is made up of tiny particles that move all the time. ï· All matter is made up of tiny, invisible, moving particles.
A eukaryote (/juËËkÃ¦ri.oÊt/ or /juËËkÃ¦riÉt/) is any organism whose cells have a cell nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota.
A eukaryote is a type of cell (or unicellular organism) that possesses a nucleus and membrane-bound organelles, in contrast to prokaryotes (bacteria and archaea) which don't. Eukaryote means good/true nut/kernel in Greek, referring to the nucleus, while prokaryote means before nut/kernel.
